PATENT THOMAS H. HUTCHINSON, OF BROOKLYN, NEW YORK.

URlNAL-PAN.

SPECIFICATION forming part Of Letters Patent No. 602,080, dated April12, 1898. A lication filed May 16, 1896. Serial No. 591,770. (No model.)

To aZZ whom it may concern: I Be it known that I, THOMAS H. HUTOHIN-SON, a citizen of the United States, residingat Brooklyn, in the countyof Kings and State of New York, have invented anew and usefulImprovement .in Urinal-Pans, of which the following is a fullspecification, enabling others skilled in the art to which it pertainsto make the same.

My invention relates to urinal-bowls, and particularly to such as areprovided with tanks or other water-supply as a means for flushing thebowl with water and thus removing the contents.

.The objects of the invention are, first, to provide for so flushing theurinal-bowl that all danger of splashing on the clothing will beavoided, and, secondly, to provide an effective means whereby the bowlmay be cleansed, and by its construction with a trap integral with thedevice prevent the odor from rising through the stand-pipe after theflush. These objects I accomplish by means of the device illustrated inthe accompanying drawings, referred to herein, like letters referring tolike parts in eachfigure thereof.

Figure 1 is a perspective front View of a ,urinal embodying myinvention. Fig. 2 is a vertical section of the same through the line a:a; in Fig. 1. Fig. 3 is a transverse medial section through the line z zin Fig. 1.

The device is preferably made in the usual form of urinal-bowls with aprojecting central front portion. I

A represents the main bowl of the urinal,

which is provided with a primary upper pan A having a dam A. This dam isprovided with a lip A at its inner edge, which is reinforced by thebrace A andprojects downwardly, the lower part dipping into thesecondary and lower pan B--that is to say, its lowest point being belowthe level of the outer end or dam B, so that when the pan B is filledwith water the lip of the apron will extend below the surface thereof.This construction of the primary and secondary pans with the lower partsof the lip or apron of the primary pan dipping into the deeper portionof the secondary pan, the dam of which is higher than the lower edge ofthe apron of V the primary pan, forms a complete trap when the pan is inuse. Fig. 2 illustrates this formation.

At about the center of the part where the secondary pan is joined to therear wall and slightly above the level of the pan B is the orifice F ofthe vertical flush-pipe F, through which the water in the said pipe isdischarged This flush-pipe F takes place sufficient water is allowed topass to cleanse the inner side of the rear Wall of the bowl. Thesupply-pipe H also communicates through this auxiliary chamber with thehollow rim E, which is substantially of the ordinary flushing-rimconstruction,being provided with perforations e to admit of Waterpassing through them and down thesides of the primary pan throughout itscircumference on the inner side of the bowl. part of the bowl A, at thepoint where the pan A is joined to the rim E, there is a perforation E,much larger than the others. This perforation E is at a point wherethestreams from both sides of the rim meet, and it is adapted to flushthe primary pan and force its contents backward and over the dam A intothe lower pan B, from whence it passes through the channel- O'into thedischargepipe D. Y

The supply-pipe H and the discharge-pipe D are secured to the 'bowl inthe ordinary manner, and the bowl is provided with'perforatedwing-flanges J J for the purposeof attaching it to the wall of abuilding. The channel 0 is formed by the interstice between the pan Band the outer wall I of the bowl. V

It willalso be noted that when the trap is flushed the Water, togetherwith what matter may be contained in the upper dam,'passes At the frontfrom the front to the rear, away from the person using the bowl, wherebythe danger of the clothing of the latter becoming splattered is avoided.

The operation of this device is as follows:

When it is desired to flush the bowl, the wa-,

ter is admitted through the supply-pipe H by any suitable means, such asa pull or cook, to the auxiliary chamber G, whence it distributes itselfinto either or both arms of the flush-rim E and flush-pipe F, a smallportion of it passing through the perforations g in the bottom of thechamber and flowing over the inner side of the rear wall K. The waterpassing through the rim E is forced by the pressure through theperforations e and flows over the sides of the bowl into the pans A andB, while the jet of water issuing from the orifice E flushes the pan Aforcing its contents over the dam A and into the secondary pan B.Simultaneously the water passing through the flush-pipe F forces itselfthrough the orifice F, flushing the pan B and forcing its contents tooverflow the dam B into the channel 0, whence it is carried off by theoutlet-pipe D. When the water is turned off in the supply-pipe and thepressure thus removed, the water remaining in the rim E and theflush-pipe F settles into the pans A and B, the pan A overflowing, whenit receives more than it can retain, into the pan B, and the pan Binturn overflowing into the channel 0. All the contents of the two bowlsare in this manner removed and replaced by clean water. It will bereadily seen that when the water has thus settled the lower end of thelip A will be immersed in the water of the pan B, where it forms aperfect trap, sealing the communication between the discharge-pipe Dthrough the channel C and the upper parts of the bowl. This arrangementprevents any offensive odors from rising from the discharge-pipe.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The herein-described urinal-bowl having upper and lower pansintegraltherewith, said upper pan being designed to be flushed from the fronttoward the rear, and said lower pan being flushed from the rear towardthe front, the forward portion of said lower pan being extended beneaththe inner portion of said upperlpan, a depending portion of said upperpan being beneath the level of the water of the lower pan, and an outletwith which said lower pan communicates, the rear wall of the bowlextending above the point where the rearward flush enters, substantiallyas set forth.

2. The herein-described urinal-bowl, having upper and lowerpans'integral therewith forming passage-ways between themselves andbetween said lower pan and the bottom of the urinal, and an outlet intowhich said latter passage-way opens, said upper pan being flushed fromthe front toward the rear, and said lower pan from the rear toward thefront, said upper pan being provided at its rear end with a dependingportion which intercepts the water-level of said lower pan the rear wallof the bowl extending above the point where the rearward flush enters,substantially as set forth.

3. The herein-described urinal-bowl having an upper waterchamber, adepending pipe leading therefrom, a hollow rim also leading fronrsaidchamber and slotted at the front end of the bowl, upper and lower pansintegral with said bowl, said upper pan extending from the front end ofsaid bowl to near the rear wall thereof, and said lower pan extendingfrom said rear wall to near the front wall of said bowl, said dependingpipe opening onto said lower pan beneath the water-level thereof, andsaid upper pan having at its rear end a depending portion'whichintercepts the water-level of said lower pan, substantially as setforth.

4. The herein-described urinal-bowl having an upper water-chamber, adepending pipe leading therefrom, apertures being formed in the bottomof said chamber, a hollow rim also leading from said chamber and havinga series of perforations facing the side walls of the bowl, and a slotat the front end of the bowl, upper and lower pans integral with saidbowl, said upper pan extending from the front end of said bowl to nearthe rear wall thereof, and said lower pan extendin g from said rear wallto near the front wall of said bowl,said depending pipe opening ontosaid lower pan beneath the water-level thereof, and said upper panhaving at its rear end a depending portion which intercepts thewater-level of said lower pan, substantially as set forth.
